how to write nested string format?

Question

I used below for string formatting in plotly.

texttemplate='%{text:.2f}'

now I like to set num of digit as a variable so I have to use nested string format like this, it didn't work. Thanks for your help.

num_gigit=f(key)
texttemplate='%{text:.{num_digit}f}'

~~I would try to use the round function: texttemplate='%{round(text, num_digit)}'~~

Edit: The following works:

texttemplate='%{text:.' + str(num_digit) + 'f}'

sorry it doesn't work, not sure why?

Do you need to keep the percentage sign and curly brackets for plotly? If so: texttemplate='%{' + str(round(text, num_digit)) + '}' Otherwise: texttemplate=str(round(text, num_digit))'

I just thought of another possible solution: texttemplate='%{text:.' + str(num_digit) + 'f}'
